'parallel and substantially uniform corrugations or alternate ridges and furrovvs extending over its surface which represent the folds or pleats of a fabric, Which may be omitted if desired, and having an outer glazed surface and an inner dull surface, and an inner coating of a suitable coloring material of any desired color. Imay also, if desired, provide protruding vbeads extending transversely of such corrugations and colored With different pigment thereby simulating the colored braids on such shade.

For the purpose of illustrating my invention, I have shown in the accompanying drawings forms thereof Which are at present preferred by me, since they Will give in practice satisfactory and reliable results, although it is to be understood that the various instrumentalities of Which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Referring to the drawings Figure 1, represents an elevational vievs7 of a novel shade embodying my invention.

Figure 2, represents a section on line 2 2 of Figure l.

Referring to the drawings in which similar numerals of reference. indicate corresponding part-s.

l designates a glass shade embodying my invention, supported by means of a metal shade holder 2, of any suitable construction and having positioned Within it a suitable electric incandescent bulb 3. A series of parallel corru'gations or alternate ridges and ILLUMINATING SHADE.

furroivs .ll are provided throughout the sui'- face oftl e shade, as shown in the figures, Whichareof a size or Width depending .on the size of the shade, so as. to simulate the folds or pleats of afabric-dravvn tautlongitudinally of such pleats or folds, upon' con.- cealed metallic frame, as is commonly; the practice. t Y

rf'he outer surface 5, of the shade, is glazed so as to rproduce a reiiecting surface Whilezthe innerl surface 6 thereof is ofa dull finish and carries, a coating 7 of anysuitable pigment orl coloring matter, applied .theretoinA any suitable manner. pose is preferably aclear colorless crystal glass, and the shade is die pressed and preferably of the contour of a truncate-d cone. The corrugations are preferably made slightly irregular or of' slightly varying Widths,

so as more closely to simulate the irregularif ties of the pleats and folds of a silk shade.

By this novel combination in a glass shade,

of a series of ccrrugations and an outer re-Y fleeting surface and the inner dull surface carrying a coating or layer ofpigment, there ris obtained a glass illuminating shade, having the general appearance and artistic effect of a silk shade, when light is transmitted therethrough, from Within the shade. This effect, is a result of this nevel combination of features, and is produced by the reflection and refraction of the light passing through the glass, augmented by the cuter corrugated surface thereof.

lf desired, there may be 'provided suitable up per and lower transverse protruding beads, such as 8 and 9, Which are also preferably colored and provided with an outer stippled, or otherwise decorated surface, so as to simulate a colored braiding commonly employed "v on silk shades. The transverse beads 8 and 9 may be of the same or of a dierent color than the body of the shade. Since the beads 8 and 9 do not have the outer smooth reiiecting surface, they will be quite different and will stand out in contrast to the corrugated surface of the shade, which is of a silky appearance.

lt will now be apparent that I have devised a novel and useful illuminating shade Which The .glassfused for this pursuch embodiment is susceptible of modifica-V tion in variouspartieulars Without departing from the spirit or scope of the invention or v A sacrificing any of its advantages.

Having thus described my invention, What I elaim'as new and desire to secure by Letters Patent, is-:`- Y

An illuminating glass shade, having the contour of a truncated eone open at both ends with aseries of alternate longitudinally leX- Y tending ridges and-furrovvs Vextendlng overr its surface Vsubstantiall Y parallel and of sub-V stantiallyfuniform Wi th, the outer surface of said shade being glazed and of a reiecting character Whilethe inner surface thereof is dull and has a eoating of pigment, and upperV and lower'annulai stipp'le beads of dierent diameters extending transversely aerosssaid furrows and ridges, whereby said shade Will7 by light transmitted through it from Within, simulate a silkshade. i
